Curated list of the top 30 GIS tools and platforms that enable rapid mapping, data integration, and situational awareness during emergencies.
Get targeted exposure with custom position pinning and highlighted placement.
Desktop GIS for advanced spatial analysis, 3‑D visualization, and real‑time data integration—ideal for creating detailed disaster impact maps.
Cloud‑based GIS platform for sharing maps, dashboards, and data layers with responders and the public in seconds.
Real‑time dashboard that aggregates live feeds (weather, sensor, social media) into actionable visualizations for incident commanders.
Mobile app that combines map viewing, data collection, and location tracking for field teams operating in disaster zones.
Form‑based data capture tool for rapid damage assessments, needs surveys, and resource requests, with offline capability.
Legacy mobile data collection app (now part of Field Maps) for gathering geotagged observations directly into ArcGIS.
Pre‑packaged maps, data, and tools (e.g., Hurricane, Flood, Wildfire templates) that accelerate response planning and coordination.
Open‑source desktop GIS with extensive plugins for raster/vector analysis, suitable for low‑budget emergency operations.
Planet‑scale geospatial analysis platform for processing satellite imagery (e.g., flood extent, burn severity) in near real‑time.
Customizable web‑mapping SDK and APIs that enable fast creation of interactive disaster maps and mobile navigation tools.
Location intelligence platform with built‑in data enrichment, spatial analytics, and shareable dashboards for crisis teams.
Powerful open‑source GIS for raster processing, hydrological modeling, and terrain analysis—useful for flood modeling.
Open‑source system offering a large toolbox for terrain analysis, watershed delineation, and hazard modeling.
Open‑source server for publishing OGC‑compliant map services (WMS/WFS) that enable interoperable data sharing among agencies.
JavaScript library for building web‑based interactive maps that can integrate multiple disaster data sources.
Desktop GIS with strong cartographic capabilities and easy‑to‑use spatial queries for rapid situational reports.
